Waste dump comprising a storage space with impermeable wall of material with pozzolanic properties

摘要

A waste dump (1) for waste material (8) consisting of a partially underground tank (2) having rigid hydraulically set walls (3) with self-restoring capacity when cracks (5) occur in said walls.;The walls may consist of rigid concrete having on their inner side a self-restoring layer (4) when cracks occur, but the walls may also completely consist of such a self-restoring layer.;The self-restoring capacity of the layer and wall respectively is obtained by the presence of still hydraulically settable material with pozzolanic properties in said hydraulically set layer and/or wall.;The self-restoring layer is formed from ground granulated blast furnace slag with fine or coarse blast furnace slag granulate, the ground blast furnace slag may be partially replaced with ground fly ash and the coarse or fine blast furnace may be replaced with gravel.;The tank (2) may also be covered by a rigid cover (7) having the abovementioned self-restoring properties obtained by means of materials with pozzolanic properties.
